I bought this book because I wanted to do a lot of studying without internet or a computer. (ex: on a plane). It served that purpose. I write a cert book myself and it is hard to write an errata free book. However, the problems I have go beyond errata. Read this review and see if they are things that bother you.
There were a bunch of errata which I didn't log. This is to give you a feel for the quality type issues. Also, the book wasn't written by anyone in particular. It was assembled from different places which probably explains some of this.
page 18 – There's a table that claims to include the exam domains and weights. The weights are not included
page 131 – the wrapping makes it hard to read
page 155 - “policies” is in the same bulleted list twice
page 212 - “Note: Log into a CentOS 7 Linux virtual machine and get Terraform install on it” - this Is not on a page about Linux so it looks like a note to the author that wasn't removed.
Topics are covered more than once. For example, how to install Terraform is in ch 3 and ch 5.
Various inconsistencies like “terraform dot workspace” and “tf underscore log” vs “tf_log”.
Not all review questions are covered in the chapter. For example SaltStack is in the chapter 1 review questions, but not in the chapter
The book references dumps, but I think this is a language issue. They look like practice questions and not dumps.
I did like that the concepts were covered and bold was used for important code. I also like that there were screenshots of the lab since I didn't have computer on hand when studying. The review questions helped reinforce the material in each chapter.
If you can live with errors and the above problems, go for it.
